molecules have more than 1 _______ but compounds have more than 1 _________.
atom, element
What has a high ___________ meaning it takes a lot of energy to change it to a gas
High heat of vaporization
The single unit monomer of a carbohydrate
monosaccharide, glucose
Which subatomic particle determines the identity of an element?
What is a proton
Results when electrons are shared between two atoms
What is a covalent bond
Blood is an example of this type of mixture because it has solid particles within a liquid
suspension
Bases form this type of ion in solution.
OH-, hyroxide
These make up cell membranes
phospholipids
What is the difference between atomic number and atomic mass?
Number is just the protons. Mass is protons & neutrons together
Polar bonds means electrons are share ______ while non-polar means electrons are shared _______.
unequally; equally
The word that describes how close or spread out particle are
concentration
This substance resists a change in pH
buffer
Enzymes are __________ made up of ______ and bind to a specific _________
proteins; amino acids, substrate
Which sub atomic particle is responsible for determining the isotope of that element
neutron
These bonds are a result of polar molecules being attracted to one another. They are found between molecules of water & DNA
Hydrogen bonds
the term that describe a solution or mixture where the particle are spread equally throughout
homogeneous
This reaction results in the formation of a salt and water. It happens when an acid and a base are mixed.
neutralization
DNA is double stranded, but the code is in the sequence of the bases, what are the bases found in DNA
